I fitted them to mine a few weeks ago, and I'm very pleased with them. Not sure about the legality, and I don't care, as they're very effective in making me more visible. My bike's a couple of years away from needing an MoT, but I'm fairly certain that, when the time comes, the examiner will take the same view. If not, the running/tail/brake light functions can easily be disconnected. I installed an LED-compatible rectifier instead of the resistors that came with the Blinkers (for a neater install, and not having to find space for the resistors), and used easily-detachable bullet connectors instead of the crappy Scotchlok connectors that were in the box.
